The battery unit includes two rows of battery cells and a thermal conduit disposed in between them and directly the two rows. In an embodiment, the thermal conduit includes a flexible surface, establishing direct contact with a portion of the surface area around a portion of the circumference of each battery cell wherein heat transfer may take place. Aspects of the present disclosure can include a thermal circuit configured to provide the necessary media to allow for the heat transfer to take place. This is so, at least in part, for the thermal conduit to precondition the battery cells of the electric aircraft and facilitate the precondition of the battery cells.

In an embodiment, the battery management apparatus may precondition the battery pack of an electric aircraft by facilitating the flow of media while the electric aircraft is on the ground, wherein the flow of media is to cool the battery pack and its batteries. In this way, a fast-deployable assembly to remove heat from the battery pack during ground-based recharging is achieved. Aspects of the present disclosure can incorporate a ground-based cooling component where the media for cooling is provided from. In an embodiment, the apparatus may include mechanisms to connect to the ground-based cooling component. In some embodiments, the ground-based cooling component may be integrated with the electric aircraft. In another embodiment, the apparatus may facilitate the flow of media, wherein the battery pack needs to be heated for certain operations. The apparatus may enable an electric aircraft battery module to maintain a sufficient temperature during recharging, wherein the sufficient temperate allows the electric aircraft to begin a flight missing immediately after battery charging is complete. In an embodiment, the apparatus may be integrated in an electric vehicle, such as electric aircraft.

Aspects of the present disclosure can also be used to precondition the battery pack of an electric aircraft during flight. In an embodiment, the apparatus may include a supplemental cooling component designed to provide the media and facilitate the flow of media for the precondition of the battery pack prior to or following the landing of the electric aircraft. The supplemental cooling component can be used as a temporary storage for media to be used to facilitate the flow of media within the battery pack.

In another embodiment, the apparatus may include cowl flaps incorporated onto the media channel and/or the exterior of the battery pack and electric aircraft to circulate outside airflow into the media channel and facilitate the flow of media inside and out of the electric aircraft and battery pack. This is so, at least in part, if the battery pack needs to be preconditioned during flight, the cowl flaps can be activated to open and expose the media channel for outside air to enter for airflow circulation and expel high temperature media out. In another embodiment, the supplemental cooling component that may be used to store excess media may reach its maximum capacity in which it must evacuate the excess media. The cowl flaps may allow for the excess media to evacuate the battery pack and the electric aircraft.

Aspects of the present disclosure can also include measures to detect media discharge or leaks.

This is so, at least in part, to determine if some corrective measure needs to be taken to address and/or compensate for such media discharge or leaks. For example, the media channel may receive less than required media due to some mechanical fault of the apparatus. The apparatus may be configured to enable the cowl flaps during flight to compensate for the fault and precondition the battery cells using outside airflow. Aspects of the present disclosure can incorporate a computing device communicatively, connected to the electric aircraft. In an embodiment, a pilot of the electric aircraft may govern the preconditioning and functions of the apparatus. In another embodiment, the computing device may enable the pilot to perform any corrective measures in various situations.

In one or more embodiments, and still referring to FIG. 3 , a plurality of MMUs 300 may be configured to monitor battery module 308 and/or battery cell 312. For instance, and without limitation, a first MMU 300 a may be position at one end of battery module 308, and a second MMU 300 b may be positioned at an opposing end of battery module 308. This arrangement may allow for redundancy in monitoring of battery cell 312. For example, and without limitation, if first MMU 300 a fails, then second MMU 300 b may continue to work properly and monitor the operating condition of each battery cell 312 of battery module 308. In one or more embodiments, MMU 300 may monitor the operating condition of a plurality of battery cells, as shown in FIG. 3 .

In one or more embodiments, and still referring to FIG. 3 , MMU 300 is configured to detect a measurement parameter of battery module 308. For the purposes of this disclosure, a “measurement parameter” is detected electrical or physical input, characteristic, and/or phenomenon related to a state of battery pack 304 and/or components thereof. For example, and without limitation, a measurement parameter may be a temperature, a voltage, a current, a moisture level/humidity, a gas level, or the like, as discussed further in this disclosure. In one or more embodiments, MMU 300 may be configured to perform cell balancing and/or load sharing during the charging of battery pack 304. Cell balancing may be used when a battery module includes a plurality of battery cells 312. Cell unbalance includes variances in charge and discharge of each battery cell depending on an operating condition of each battery cell 312. Cell unbalance may result in damage, such as degradation or premature charge termination, of a battery cell. For example, a battery cell with a higher SOC than other battery cells may be exposed to overvoltage during charging. Cell balancing may include compensating for a variance in SOC, internal impedance, total chemical capacity, or the like. For instance, MMU 300 may perform cell balancing for SOC and thus regulate voltage input of battery cells 312. For instance, and without limitation, charging of battery pack 304 may be shared throughout a plurality of battery cells 312 by directing electrical power through balance resistors and dissipating voltage through resistors as heat. For example, and without limitation, resistor may include a nonlinear resistor, such as a thermistor 320. Thermistor 320 may be configured to provide cell balancing by reducing a voltage supplied to a battery cell of the battery module. The reduction in the voltage supplied to the battery cell may be achieved via heat dissipation. In one or more non-limiting embodiments, MMU 300 may detect the charge of each battery and thermistors 320 of MMU 300 may be configured to reduce a current and/or voltage supplied to a battery cell 312 as a function of a temperature of the thermistor. For example, and without limitation, if a battery cell is being overcharged then the temperature of the connected circuit and thermistor may also experience and increase in temperature; as a result the thermistor may increase in resistance and a fraction of the supplied voltage across the thermistor will also change, which results in a decrease in voltage received by the battery cell. In this manner, battery cells 312 may be charged evenly during recharging and/or charging of battery pack 304 by, for example, a charging station or an electric grid. For example, and without limitation, battery cells with a lower SOC will charge more than battery cells with a greater SOC by thermistors 320 dissipating voltage to the battery cells with the greater SOC. In one or more embodiments, cell balancing may be equally distributed, where each battery cell receives an equal amount of electricity depending on how many amps are available from the charger and how many cells need to be charged. For example, and without limitation, a current may be equally distributed to each battery cell by MMU 300. In another embodiment, MMU 300 may detect an SOC of each battery cell and distribute current to each battery cell in various amounts as a function of the detected SOC of each battery cell. For example, and without limitation, MMU may detect that a first battery cell has an SOC of 30% and a second battery cell has as SOC of 80%. During recharging, the current and/or voltage to the first battery may be increased so that first battery cell is charged faster than the second battery cell. In one or more non-limiting embodiments, once first battery cell is at the same SOC as the second battery cell during recharging, distribution of current and/or voltage to each battery cell may be adjusted again so that the first battery cell and the second battery cell receive an equal charge.

With continued reference to FIG. 3 , in a non-limiting embodiment, MMU 300 is configured to monitor a temperature of battery module 308. For example, MMU 300 may include a sensor 324 configured to detect a temperature parameter of battery cell 312. Sensor 324 may be consistent with any senor as described in the entirety of this disclosure. For example, and without limitation, sensor 324 may include thermistor 320, which may be used to measure a temperature parameter of battery cell 312. As used in this disclosure, a thermistor includes a resistor having a resistance dependent on temperature. In one or more embodiments, sensor 324 may include circuitry configured to generate an MMU datum correlated to the detected measurement parameter, such as a temperature of battery cell 312 detected by thermistor 320. An “MMU datum,” as used in this disclosure, is a collection of information describing the measurement parameters of battery cell 312. In a non-limiting embodiment, MMU 300 a and MMU 300 b may generate their respective MMU datums. This is so, at least in part, to compare the MMU datum measured by MMU 300 a and the MMU datum measured by MMU 300 b. In a non-limiting embodiment, the comparison may indicate one or more discrepancies related to the measurement parameters which may further indicate some thermal event. A thermistor may include metallic oxides, epoxy, glass, and the like. A thermistor may include a negative temperature coefficient (NTC) or a positive temperature coefficient (PTC). Thermistors may be beneficial do to being durable, compact, inexpensive, and relatively accurate. In one or more embodiments, a plurality of thermistors 320 may be used to provide redundant measuring of a state of battery cell 312, such as temperature. In other embodiments, MMU 300 may also include a resistance temperature detector (RTD), integrated circuit, thermocouple, thermometer, microbolometer, a thermopile infrared sensor, and/or other temperature and/or thermal sensors, as discussed further below in this disclosure. In one or more embodiments, thermistor 320 may detect a temperature of battery cell 312. Subsequently, MMU 300 may generate a sensor signal output containing information related to the detected temperature of battery cell 312. In one or more embodiments, sensor signal output may include the MMU datum containing information representing a detected measurement parameter.

Still referring to FIG. 3 , sensor 324 may include a sensor suite 300 (shown in FIG. 3 ) or one or more individual sensors, which may include, but are not limited to, one or more temperature sensors, voltmeters; current sensors, hydrometers, infrared sensors; photoelectric sensors, ionization smoke sensors, motion sensors, pressure sensors, radiation sensors, level sensors, imaging devices, moisture sensors, gas and chemical sensors, flame sensors, electrical sensors, imaging sensors, force sensors, Hall sensors, airspeed sensors, throttle position sensors, and the like. Sensor 324 may be a contact or a non-contact sensor. For example, and without limitation, sensor 324 may be connected to battery module 308 and/or battery cell 312. In other embodiments, sensor 324 may be remote to battery module and/or battery cell 312. Sensor 324 may be communicatively connected to controller 320 of PMU 312 (shown in FIG. 3 ) so that sensor 324 may transmit/receive signals to/from controller 320, respectively, as discussed below in this disclosure. Signals, such as signals of sensor 324 and controller 320, may include electrical, electromagnetic, visual, audio, radio waves, or another undisclosed signal type alone or in combination. In one or more embodiments, communicatively connecting is a process whereby one device; component, or circuit is able to receive data from and/or transmit data to another device, component, or circuit. In an embodiment, communicative connecting includes electrically connecting at least an output of one device, component, or circuit to at least an input of another device, component, or circuit.

In one or more embodiments, and still referring to FIG. 3 , MMU 300 may include a control circuit that processes the received MMU datum from sensor 324, MMU 100 a, and/or MMU 100 b. In one or more embodiments, control circuit may be configured to perform and/or direct any actions performed by 300 and/or any other component and/or element described in this disclosure. Control circuit may include any analog or digital control circuit, including without limitation a combinational and/or synchronous logic circuit, a processor, microprocessor, microcontroller, any combination thereof, or the like. In one or more embodiments, control circuit may be solely constructed from hardware; thus, control circuit may perform without using software. Not relying on software may increase durability and speed of control circuit while reducing costs. For example, and without limitations, control circuit may include logic gates and/or thermistors, as discussed further in this disclosure. In some embodiments, control circuit 328 may be integrated into MMU 300, as shown in FIG. 3 . In other embodiments, control circuit 328 may be remote to MMU 300. In one or more nonlimiting exemplary embodiments, if the MMU datum of a temperature of a battery module 308, such as at a terminal 332, is higher than a predetermined threshold, control circuit 328 may determine that the temperature of battery cell 312 indicates a critical event and thus is malfunctioning. For example, a high voltage (HV) electrical connection of battery module terminal 332 may be short circuiting. If control circuit 328 determines that a HV electrical connection is malfunctioning, control circuit 328 may terminate a physical and/or electrical communication of the HV electrical connection to prevent a dangerous or detrimental reaction, such as a short, that may result in an electrical shock, damage to battery pack 304, or even a fire. Thus, control circuit 328 may trip a circuit of battery pack 304 and terminate power flow through the faulty battery module 308 until the detected fault is corrected and/or the excessively high temperature is no longer detected. Temperature sensors, such as thermistor 320 may assist in the monitoring of a cell group's overall temperature, an individual battery cell's temperature, and/or battery module's temperature, as just described above.

In one or more embodiments, and still referring to FIG. 3 , MMU 300 may not use software. For example, MMU 300 may not use software to improve reliability and durability of MMU 300. Rather, MMU 300 may be communicatively connected to a remote computing device, such as computing device 800 of FIG. 8 . In one or more embodiments, MMU 300 may include one or more circuits and/or circuit elements, including without limitation a printed circuit board component, aligned with a first side of battery module 308 and the openings correlating to battery cells 312. In one or more embodiments, MMU 300 may be communicatively connected to a remote processing module, such as a controller. Controller may be configured to perform appropriate processing of detected temperature characteristics by sensor 324. In one or more embodiments, controller ** may include an application-specific integrated circuit (ASIC), field-programmable gate array (FPGA), a central processing unit (CPU), readout integrated circuit (ROIC), or the like, and may be configured to perform characteristic processing to determine a temperature and/or critical event of battery module 308. In these and other embodiments, controller may operate in conjunction with other components, such as, a memory component, where a memory component includes a volatile memory and/or a non-volatile memory.

In one or more embodiments, and still referring to FIG. 3 , each MMU 300 may communicate with another MMU 300 and/or a controller via a communicative connection 336. Each MMU may use a wireless and/or wired connection to communicated with each other. For example, and without limitation, MMU 300 a may communicate with an adjacent MMU 300 a using an isoSPi connection 304. As understood by one skilled in the art, and isoSPI connection may include a transformer to magnetically connect and electrically isolate a signal between communicating devices. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of the various embodiments of communication in the context of sensors.

Referring now to FIG. 4 , an exemplary embodiment of a battery pack 400 with a plurality of battery modules 404 is illustrated. Battery pack 400 may be consistent with any battery pack as described herein. Battery module 404 may be consistent with any battery module as described herein. In a non-limiting embodiment, Battery pack 400 may be configured to facilitate the flow of thermal media through each battery module 400 of the plurality of battery modules to cool battery pack 400. Battery pack 400 can include one or more battery modules 404. Battery pack 400 may be configured to house and/or encase one or more battery modules. As an exemplary embodiment, FIG. 4 illustrates 7 battery modules 404 creating battery pack 400. In an embodiment, each battery module 400 of the plurality of battery modules can include one or more battery cells 408. Each battery module 404 may be configured to house and/or encase one or more battery cells 308. Each battery cell of the plurality of battery cells 408 may include any battery cell as described in further detail in the entirety of this disclosure. Battery cells 408 may be configured to be contained within each battery module 404, wherein each battery cell 408 is disposed in any configuration without limitation. As an exemplary embodiment, FIG. 4 illustrates 240 battery cells 408 housed within each battery module 404, however, a person of ordinary skill in the art would understand that any number of battery units 408 may be housed within each battery module 404 of battery pack 400. Further, each battery module of the plurality of battery modules 404 of battery pack 400 includes first thermal circuit 412.

Referring now to FIG. 5 , an exemplary embodiment of a pack monitoring unit (PMU) 500 is shown in accordance with one or more embodiments of the present disclosure. In one or more embodiments, PMU 500 may be implemented in a battery management system (shown in FIG. 3 ) to monitor a battery pack 504 and/or components of battery pack 504. In one or more embodiments, PMU 500 may receive a condition parameter from a sensor that is configured to detect a condition parameter of battery pack 504. In one or more embodiments, PMU 500 may include a sensor. In other embodiments, sensor may be remote to PMU 500, for example and without limitation, a sensor of a module monitor unit (MMU) 516. As used in this disclosure, a “condition parameter” is a detected electrical or physical input, characteristic, and/or phenomenon related to a state of a battery pack. For example, and without limitation, sensor 508 may measure a condition parameter, such as temperature, of a battery module terminal and/or a battery cell of battery pack 504. A condition parameter may include a temperature, a voltage, a current, a pressure, a gas level, a moisture/humidity level, an orientation, or the like, of battery pack 504 and/or a component of battery pack 504.

In one or more embodiments, condition parameter of battery module 504 may be detected by sensor 508, which may be communicatively connected to an MMU 516 that is incorporated in a battery module, as discussed further below in this disclosure. Sensor 508 may include a sensor suite 500 (shown in FIG. 5 ) or one or more individual sensors (shown in FIG. 5 ), which may include, but are not limited to, one or more temperature sensors, voltmeters, current sensors, hydrometers, infrared sensors, photoelectric sensors, ionization smoke sensors, motion sensors, pressure sensors, radiation sensors, level sensors, imaging devices, moisture sensors, gas and chemical sensors, flame sensors, electrical sensors, imaging sensors, force sensors, Hall sensors, bolometers, and the like. Sensor 508 may be a contact or a non-contact sensor. For example, and without limitation, sensor 508 may be connected to battery module and/or battery cell of battery pack 504. In other embodiments, sensor 508 may be remote to battery module and/or battery cell.

Still referring to FIG. 5 , sensor 508 may generate a measurement datum, which is a function of a detected condition parameter. For the purposes of this disclosure, “measurement datum” is an electronic signal representing an information and/or a parameter of a detected electrical and/or physical characteristic and/or phenomenon correlated with a state of a battery pack. For example, and without limitation, a sensor signal output includes a measurement datum. In one or more embodiments, measurement datum may include data of a condition parameter regarding a detected state of a battery cell. In one or more embodiments, measurement datum may include a quantitative and/or numerical value representing a temperature, pressure, moisture level, gas level, orientation, or the like. For example, and without limitation, a measurement datum may include a temperature of 75° F. In one or more embodiments, sensor 508 is configured to transmit measurement datum to PMU 500. PMU 500 is configured to receive measurement datum and process the received measurement datum. Though sensor 508 is described as providing one or more sensors, PMU 500 may also include a sensor that detects a parameter condition of battery pack 504 and generates a measurement datum to transmit to controller 512. For example, PMU 500 may include a pressure sensor 524, a real time clock (RTC) sensor 528 that is used to track the current time and date, a humidity sensor 532, an accelerometer/IMU 536, or other sensor 540.

Still referring to FIG. 5 , PMU 500 includes a controller 512. Sensor 508 may be communicatively connected to controller 512 of 500 so that sensor 508 may transmit/receive signals to/from controller 512. Signals, such as signals of sensor 508 and/or controller 512, may include electrical, electromagnetic, visual, audio, radio waves, or another undisclosed signal type alone or in combination. In one or more embodiments, communicatively connecting is a process whereby one device, component, or circuit is able to receive data from and/or transmit data to another device, component, or circuit. In an embodiment, communicative connecting includes electrically connecting at least an output of one device, component, or circuit to at least an input of another device, component, or circuit. In one or more embodiments, controller 512 is configured to receive measurement datum from sensor 508. For example, PMU 500 a may receive a plurality of measurement data from MMU 516 a (shown in FIG. 5 ). Similarly, PMU 500 b may receive a plurality of measurement data from MMU 516 b (shown in FIG. 5 ). In one or more embodiments, PIM 500 receives measurement datum from MMU 516 via a communication component 544. In one or more embodiments, communication component 544 may be a transceiver. For example, and without limitation, communication component 544 may include an isoSPI communications interface.

In one or more embodiments, controller 512 of PMU 500 is configured to identify an operating condition of battery module 508 as a function of measurement datum. For the purposes of this disclosure, an “operating condition” is a state and/or working order of a battery pack and/or any components thereof. For example, and without limitation, an operating condition may include a state of charge (SOC), a depth of discharge (DOD), a temperature reading, a moisture/humidity level, a gas level, a chemical level, or the like. In one or more embodiments, controller 512 of PMU 500 is configured to determine a critical event element if operating condition is outside of a predetermined threshold (also referred to herein as a “threshold”). For the purposes of this disclosure, a “critical event element” is a failure and/or critical operating condition of a battery pack and/or components thereof that may be harmful to the battery pack and/or corresponding electric aircraft. In one or more embodiments, a critical event element may include an overcurrent, undercurrent, overvoltage, overheating, high moisture levels, byproduct presence, low SOC, high DOD, or the like. For instance, and without limitation, if an identified operating condition, such as a temperature reading of 50° F., of a battery cell of battery pack 504, is outside of a predetermined threshold, such as 5° F. to 90° F., where 75° F. is the temperature threshold and 90° F. is the upper temperature threshold, then a critical event element is determined by controller 512 of TAU 500 since 50° F. is beyond the lower temperature threshold. In another example, and without limitation, PMU 500 may use measurement datum from MMU 516 to identify a temperature of 95° F. for a battery module terminal. If the predetermined threshold is, for example, 90° F., then the determined operating condition exceeds the predetermined threshold, and a critical event element is determined by controller 512, such as a risk of a short at the terminal of a battery module 504. As used in this disclosure, a “predetermined threshold” is a limit and/or range of an acceptable quantitative value and/or combination of values such as an n-tuple or function such as linear function of values, and/or representation related to a normal operating condition of a battery pack and/or components thereof. In one or more embodiments, an operating condition outside of the threshold is a critical operating condition that indicates that a battery pack is malfunctioning, which triggers a critical event element. An operating condition within the threshold is a normal operating condition that indicates that battery pack is working properly and that no action is required by PMU 500 and/or a user. For example, and without limitation, if an operating condition of temperature exceeds a predetermined threshold, as described above in this disclosure, then a battery pack is considered to be operating at a critical operating condition and may be at risk of overheating and experiencing a catastrophic failure.

In one or more embodiments, controller 512 of PMU 500 is configured to generate an action command if critical event element is determined by controller 512. For the purposes of this disclosure, an “action command” is a control signal generated by a controller that provides instructions related to reparative action needed to prevent and/or reduce damage to a battery back, components thereof, and/or aircraft as a result of a critical operating condition of the battery pack. Continuing the previously described example above, if an identified operating condition includes a temperature of 95° F., which exceeds predetermined threshold, then controller 512 may determine a critical event element indicating that battery pack 504 is working at a critical temperature level and at risk of catastrophic failure, such as short circuiting or catching fire. In one or more embodiments, critical event elements may include high shock/drop, overtemperature, undervoltage, high moisture, contactor welding, SOC unbalance, and the like. In one or more embodiments, an action command may include an instruction to terminate power supply from battery pack 504 to electric aircraft, power off battery pack 504, terminate a connection between one or more battery cells 504, initiate a temperature regulating system, such as a coolant system or opening of vents to circulate air around or through battery pack 504, or the like. In one or more embodiments, controller 512 may conduct reparative procedures via action command after determining critical even element to reduce or eliminate critical element event. For example, and without limitation, controller 512 may initiate reparative procedure of a circulation of a coolant through a cooling system of battery pack 504 to lower the temperature if a battery module if the determined temperature of the battery module exceeds a predetermined threshold. In another example, and without limitation, if a gas and/or chemical accumulation level is detected that is then determined to exceed a predetermined threshold, then high voltage disconnect may terminate power supply connection 512. According to some embodiments, a vent of battery pack 504 may be opened to circulate air through battery pack 504 and reduce detected gas levels. Additionally, vent of battery module 504 may have a vacuum applied to aid in venting of ejecta. Vacuum pressure differential may range from 0.1″ Hg to 36″ Hg.

In one or more embodiments, a critical event alert may be generated by controller 512 of PMU 500 in addition to an action command. The critical event alert may include a lockout feature, which is an alert that remains even after rebooting of the battery pack and/or corresponding systems. Lockout feature may only be removed by a manual override or once the critical event element has ceased and is no longer determined by controller 512. In one or more embodiments, controller 512 may continuously monitor battery pack 504 and components thereof so that an operating condition is known at all times.

In one or more embodiments, controller 512 may include a computing device, which may be implemented in any manner suitable for implementation of a computing device as described in this disclosure, a. microcontroller, a logic device, a central processing unit (CPU), a microprocessor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a control circuit, a combination thereof, or the like. In one or more embodiments, output signals from various components of battery pack 504 may be analog or digital. Controller 512 may convert output signals from MMU 500, sensor 508, and/or sensors 524,128,132,136,140 to a usable form by the destination of those signals. The usable form of output signals from MMUs and/or sensors, through processor may be either digital, analog, a combination thereof, or an otherwise unstated form. Processing may be configured to trim, offset, or otherwise compensate the outputs of sensor. Based on MMU and/or sensor output, controller can determine the output to send to a downstream component. Processor can include signal amplification, operational amplifier (Op-Amp), filter, digital/analog conversion, linearization circuit, current-voltage change circuits, resistance change circuits such as Wheatstone Bridge, an error compensator circuit, a combination thereof or otherwise undisclosed components. In one or more embodiments, PMU 500 may run state estimation algorithms. In one or more embodiments, PMU 500 may communicate with MMU 516 and/or sensor 508 via a communication component 544. For example, and without limitation, PMU may communicate with MMU 512 using an isoSPI transceiver.

In one or more embodiments, controller 512 may be designed and/or configured to perform any method, method step, or sequence of method steps in any embodiment described in this disclosure, in any order and with any degree of repetition. For instance, controller 512 may be configured to perform a single step or sequence repeatedly until a desired or commanded outcome is achieved; repetition of a step or a sequence of steps may be performed iteratively and/or recursively using outputs of previous repetitions as inputs to subsequent repetitions, aggregating inputs and/or outputs of repetitions to produce an aggregate result, reduction or decrement of one or more variables such as global variables, and/or division of a larger processing task into a set of iteratively addressed smaller processing tasks. controller 512 may perform any step or sequence of steps as described in this disclosure in parallel, such as simultaneously and/or substantially simultaneously performing a step two or more times using two or more parallel threads, processor cores, or the like; division of tasks between parallel threads and/or processes may be performed according to any protocol suitable for division of tasks between iterations. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various ways in which steps, sequences of steps, processing tasks, and/or data may be subdivided, shared, or otherwise dealt with using iteration, recursion, and/or parallel processing.

Referring again to FIG. 5 , PMU 500 may include a memory component 520 configured to store data related to battery pack 504 and/or components thereof. In one or more embodiments, memory component 520 may store battery pack data. Battery pack data may include generated data, detected data, measured data, inputted data, determined data and the like. For example, measurement datum from MMU 512 and or a sensor may be stored in memory component 520. In another example, critical event element and/or corresponding lockout flag may be stored in memory component 520. Battery pack data may also include inputted datum, which may include total flight hours that battery pack 504 and/or electric aircraft, such as electric aircraft 508, have been operating, flight plan of electric aircraft, battery pack identification, battery pack verification, a battery pack maintenance history, battery pack specifications, or the like. In one or more embodiments, battery pack maintenance history may include mechanical failures and technician resolutions thereof, electrical failures and technician resolutions thereof. In one or more embodiments, memory component 520 may be communicatively connected to sensors, such as sensor 508, that detect, measure, and obtain a plurality of measurements, which may include current, voltage, resistance, impedance, coulombs, watts, temperature, moisture/humidity, or a combination thereof. Additionally or alternatively, memory component 520 may be communicatively connected to a sensor suite consistent with this disclosure to measure physical and/or electrical characteristics. In one or more embodiments, memory component 520 may store the battery pack data that includes a predetermined threshold consistent with this disclosure. The moisture-level threshold may include an absolute, relative, and/or specific moisture-level threshold. Battery pack 504 may be designed to the Federal Aviation Administration (FAA)'s Design Assurance Level A (DAL-A), using redundant DAL-B subsystems.

In one or more embodiments, memory component 520 may be configured to save measurement datum, operating condition, critical event element, and the like periodically in regular intervals to memory component 520. “Regular intervals”, for the purposes of this disclosure, refers to an event taking place repeatedly after a certain amount of elapsed time. In one or more embodiments, PMU 500 may include a timer that works in conjunction to determine regular intervals. In other embodiments, PMU may continuously update operating condition or critical event element and, thus, continuously store data related the information in memory component. A Timer may include a timing circuit, internal clock, or other circuit, component, or part configured to keep track of elapsed time and/or time of day. For example, in non-limiting embodiments, data storage system 520 may save the first and second battery pack data every 30 seconds, every minute, every 30 minutes, or another time period according to timer. Additionally or alternatively, memory component 520 may save battery pack data after certain events occur, for example, in non-limiting embodiments, each power cycle, landing of the electric aircraft, when battery pack is charging or discharging, a failure of battery module, a malfunction of battery module, a critical event element, or scheduled maintenance periods. In nonlimiting embodiments, battery pack 504 phenomena may be continuously measured and stored at an intermediary storage location, and then permanently saved by memory component 520 at a later time, like at a regular interval or after an event has taken place as disclosed hereinabove. Additionally or alternatively, data storage system may be configured to save battery pack data at a predetermined time. “Predetermined time”, for the purposes of this disclosure, refers to an internal clock within battery pack commanding memory component 520 to save battery pack data at that time.

Memory component 520 may include a solid-state memory or tape hard drive. Memory component 520 may be communicatively connected to PMU 500 and may be configured to receive electrical signals related to physical or electrical phenomenon measured and store those electrical signals as battery module data. Alternatively, memory component 520 may be a plurality of discrete memory components that are physically and electrically isolated from each other. One of ordinary skill in the art would understand the virtually limitless arrangements of data stores with which battery pack 504 could employ to store battery pack data.

In one or more embodiments, PMU 500 may be configured to communicate with an electric aircraft, such as a flight controller of electric aircraft, using a controller area network (CAN), such as by using a CAN transceiver 576. In one or more embodiments, controller area network may include a bus. Bus may include an electrical bus.
